Does anyone know how to fix this?

i have a ragdoll system i made a couple months ago and what i did is i put my platform standing inside the input detection and ran it after the ragdoll code

uis.InputBegan:Connect(function(inp)
	if inp.KeyCode == Enum.KeyCode.R then
		isRagdoll.Value = not isRagdoll.Value -- toggle ragdoll state
		
		if isRagdoll.Value == true then -- if ragdolling then fire the ragdoll event and force into plat stand
			ragdollEvent:FireServer(false, false)
			hum.PlatformStand = true
			hum:ChangeState(Enum.HumanoidStateType.PlatformStanding)
		else -- if getting up then fire the ragdoll event and force out of plat stand
			ragdollEvent:FireServer(true, false)
			hum.PlatformStand = false
			hum:ChangeState(Enum.HumanoidStateType.GettingUp)
		end
	end
end)

-- the 2 values in ragdollEvent are just "GettingUp" and "IsDead".
-- just small checks you dont need to worry about
